  • Abstract
    VI Engineering (VIE) has developed a novel machine vision system based on double line scan cameras and backlighting units for accurately measuring counts, times and positions of objects falling in high speed and high rate. A distinct advantage of the system is that it can distinguish clump objects that were mis-counted by the previous generation systems. Special hardware and software were designed and built to calibrate and compensate image distortion and perspective error of the lenses. The system is cost effective and meets or exceeds all the customer requirements, yet can easily be upgraded to a better performance by using higher performance cameras, lenses, and lighting without making many changes to the software
